It continuously who is using your computer using facial recognition dynamically taking steps to block your account usage, switch accounts and log a person back directly to his specific account automatically.

We faced a lot of display driver bugs, display window bugs, authentication issues all the while taking utmost care not to mess up with any core modules of Linux leading to a lot of recovery mode sessions.
